We conducted a meta-analysis of 31 studies, spanning 30 years, utilizing the WCST in participants with autism. We calculated Cohen's d effect sizes for four measures of performance: sets completed, perseveration, failure-to-maintain-set, and non-perseverative errors. The average weighted effect size ranged from 0.30 to 0.74 for each measure, all…

Complex Problem Solving (CPS) is seen as a cross-curricular 21st century skill that has attracted interest in large-scale-assessments. In the Programme for International Student Assessment (PISA) 2012, CPS was assessed all over the world to gain information on students' skills to acquire and apply knowledge while dealing with nontransparent…

Background: Research into the neuropsychology of pediatric obsessive--compulsive disorder (OCD) reveals inconsistent results, limiting the ability to draw conclusions about possible neurocognitive deficits in youth with OCD. The aim of this study was to conduct a meta-analysis of the available literature. Methods: We identified 36 studies, of…

Among some gifted education researchers, advocates, and practitioners, it is sometimes believed that there is a larger number of gifted people in the general population than would be predicted from a normal distribution (e.g., Gallagher, 2008; N. M. Robinson, Zigler, & Gallagher, 2000; Silverman, 1995, 2009), a belief that we termed the…

Examines accuracy evaluation in published testing programs of the following: J. M. Cattell; C. Spearman; A. Binet; L. M. Terman; R. M. Yerkes; E. L. Thorndike; and W. D. Scott. Developing community and consensus on testing required convergence between theorists and practitioners. (SLD)

Responding to a survey requires cognitive abilities similar to those for any other linguistic task. We argue that, when faced with a cognitively challenging task, individuals respond by simplifying the task, declining it, or performing it poorly. Using the 2003 Program for International Student Assessment (PISA 2003) data sets, we document that…

Discusses changes in testing as a result of the availability of extensive inexpensive computing and some recent developments in statistical test theory. Describes the role of the Computerized Adaptive Test (CAT) and modern Item Response Theory (IRT) in ability testing tailored to each student's knowledge and ability. (JAC)

Outlines the historical developments, current perspectives, and clinical applications of neuropsychology in evaluation, remediation, and ongoing counseling of clients and their families. Discusses assessments which allow identification of patients whose cognitive deficits have been underestimated or overestimated by other diagnostic procedures,…

Studies a new approach to ipsative analysis of children's profiles on a test of ability. Uses the Planning, Attention, Simultaneous, and Successive (PASS) processes measured by the Cognitive Assessment System to illustrate how profile analysis could be accomplished. Results suggest that the ipsative approach may offer promise for identification of…

The text focuses on identification criteria and characteristics of gifted and talented students in the context of educational programming. The section on characteristics discusses kinds of intelligence, indicators of giftedness, student characteristics that may pose difficulties for the classroom teacher (e.g., persistence, criticalness, and…

Commentary discusses two components of "The Bell Curve: Intelligence and Class Structure in American Life." First, evidence is presented demonstrating central role intelligence plays in American life; second is Spearman's g, the general factor underlying individual differences involving cognitive ability. Concludes that data does not…

Conference speakers reviewed and analyzed the current thinking underlying the basic concepts of test norms, reliability, and validity. Roger T. Lennon's paper called for more attention to the development of norming theory and summarized current norming practices and the establishment of a system which would permit comparable norms for tests which…

New approaches to assessing intelligence are discussed, as well as new intelligence tests. Among the developments are investigating neurometrics, adapting testing to the effects of technology on children, countering cultural bias, assessing social intelligence, focusing on aspects of cognitive styles, measuring learning potential, and using…

Among the many theories attempting to explain sex differences in spatial ability, one of the most highly researched is the X-linked recessive gene theory. This is a review of the major research done on that theory and shows the conflicting nature of the results. (Author)

Studies examining the performance of American Indian children on the Wechsler instruments are reviewed to provide the basis for an examination of Wechsler Intelligence Scale for Children-Revised research. Factors that potentially influence Indian performance on the Wechsler are presented. Suggestions for interpretation of the Wechsler Intelligence…
